| Summary: |
Purpose: Posterior
lamellar keratoplasty (PLK) in patients with
pseudophakic corneal oedema.
Participants and methods: The PLK have been
performed in our department since November 2004. The
studied group consisted of
8 patients (7 female and 1male), 65 to 82 years of age (mean
age: 71.5 years). Visual acuity before the surgery
ranged from 0.01 to fingers counting. All the patients
suffered from pseudophakic corneal oedema. Endothelial
keratoplasty was performed using Melles technique: a
deep stromal pocket was created across the cornea
through a 5-mm scleral access incision. Endothelium was
prepared from whole eyeballs collected according to the
EEBA guidelines. Donor disc containing healthy
endothelium was folded during the implantation procedure.
Average donor endothelial cell density was 2800 cells/mm2.
All surgeries were performed by one surgeon (EW).
Results: In two eyes conversion to PKP was
necessary. Best corrected visual acuity (BCVA) ranged
from 0.4 to 1.0 (mean
0.6 ± 0.12). Postoperative astigmatism ranged from 0.75
to 2.5 D (mean 1.8 D ± 0.34). Postoperative endothelial
cell density ranged from 1700 do 2300 cells/mm2 (mean
2200 cells/mm2 ±150). Mean Postoperative endothelial
cell loss came to 29%.
Conclusions: Posterior lamellar keratoplasty is a
feasible surgery to manage corneal endothelial disorders.
Automation of procedures by the use of laser preparation
of donor tissue and adaptation automatic microkeratomes
will increase the afterrepeating of procedures. |
